Splitting and Joining Audio Clips

You may want to use only part of the source audio file in an audio clip. Soundtrack Pro lets you split the clip into segments and use the segments in the Timeline as independent clips. You can move the segments, edit them, and split each one into additional segments. You can also easily (re)join clips.

You can split clips by using the Split command or by using the Blade (razor) and Blade All tools. Each method has advantages, depending on the situation.

Splitting Clips with the Blade Tool

Using the Blade tool, you can perform many splits consecutively without moving the playhead each time.

To split audio clips with the Blade tool
  1. Click the Blade Tool button above the Timeline.

    The pointer changes to the Blade tool pointer.

  2. Click a clip at the point where you want to split it.

    The clip is split at the point where you clicked.

Splitting Clips Across All Tracks with the Blade All Tool

Use the Blade All tool to split across all tracks.

To split audio clips on all tracks with the Blade All tool
  1. Click the Blade All Tool button above the Timeline.

    The pointer changes to the Blade All pointer.

    Note: To toggle between the Blade and the Blade All tools, hold down the Shift key while either tool is selected.

  2. Click anywhere in the Timeline where you want to split clips on all tracks.

    Note: If you use the Blade All tool in the podcast track, it cuts the podcast track as well as any audio clips that are also under the Blade All tool. However, if you use the Blade All tool in an audio track, it does not make a cut in the podcast track.

Splitting Clips with the Playhead

Using the playhead, you can split clips while a project is playing, split clips on selected tracks, and split clips without having to use the mouse.

Note: If no clips or tracks are selected, using the Split command splits all clips under the playhead.

To split selected audio clips with the playhead
  1. Set the playhead at the point where you want to split the clip, then select the clip or clips you want to split.

    You can split multiple clips in the same operation.

    Figure. Multitrack Timeline showing playhead.
  2. Choose Clip > Split (or press S).

    Every selected clip under the playhead is split into two segments. The first segment ends at the playhead position, and the second segment begins at the playhead position.

You can split an audio clip into three segments with the Timeslice tool by making a selection in the middle of the audio clip (any part not including either the beginning or the end), and then pressing the S key. The clip is split into three segments, defined by the beginning and end of the selection. For more information about the Timeslice tool, see Editing with the Timeslice Tool.

To split audio clips on selected tracks
  1. Set the playhead at the point where you want to split the clip or clips.

  2. Select the track or tracks containing the clip or clips you want to split.

  3. Choose Clip > Split (or press S).

    Every clip under the playhead on the selected tracks is split into two segments. The first segment ends at the playhead position, and the second segment begins at the playhead position.

Note: Any clip selections will supersede track selections; if both clips and tracks are selected under the playhead, Soundtrack Pro will split only the clips.

To split audio clips while playing a project
  1. Do one the following:

    • Select the clip or clips you want to split.

    • Select the track or tracks containing the clip or clips you want to split.

  2. Play the section of the Timeline containing the clip or clips you want to split.

  3. While the project is playing, press S as often as you like.

    The clip or clips are split at the playhead each time you press S.

Joining Audio Clips

You can rejoin split clips from the same original audio file that have been split using the blade tool or the Split command. Clips being joined must be adjacent to each other and in the same track.

To join audio clips
  1. Place the clips next to each other in the same track.

  2. Select the clips, then choose Clip > Join (or press Option-S).

    When you join looping files or segments of looping files, the joined file plays to the end of the source audio file before looping. The notches in the joined file indicate the end of the source audio file.
